摘要:
A TV camera lens device includes a flange back length control signal for moving a master lens group to a position of the proper flange back length in accordance with the operation of a flange back length control. It further includes a macro control signal generating device for outputting a macro control signal for moving the master lens group to a preset macro position where the master lens group is to be positioned during the macro-shooting. Then, either one of the flange back length control signal and the macro control signal is made to take preference in accordance with the operation of a selector switch, and the selected control signal is input to a control circuit. Incidentally, the macro position may be relatively defined as referenced from the position of the proper flange back length.
